How can I send HTML emails reliably using PHP and PHPMailer?
Sending HTML Email: SMTP Configuration for PHP
Although the email sending example shows using PHP to send HTML email, frustratingly, It doesn't work correctly. Specifically, it produces a blank email in Gmail with an empty file named "noname" attached.
To solve this problem, consider using the PHPMailer class. This is a popular and well-maintained PHP library designed to simplify the email sending process. With PHPMailer, you can easily create and send HTML emails, attach files, set priorities, and process attachments.
To get started, install PHPMailer through Composer:
composer require phpmailer/phpmailer
Once installed, you can write the following code to send HTML emails using PHPMailer:
use PHPMailer\PHPMailer\PHPMailer; use PHPMailer\PHPMailer\SMTP; use PHPMailer\PHPMailer\Exception; $mail = new PHPMailer(true); try { // 设置服务器的信息 $mail->isSMTP(); $mail->Host = 'smtp.example.com'; $mail->SMTPAuth = true; $mail->Username = 'username@example.com'; $mail->Password = 'password'; $mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS; $mail->Port = 587; // 设置发件人 $mail->setFrom('from@example.com', 'From Name'); // 添加收件人 $mail->addAddress('to@example.com', 'To Name'); // 设置主题和内容 $mail->isHTML(true); // Set email format to HTML $mail->Subject = 'Test HTML email'; $mail->Body = '<h1>Hello World!</h1><p>This is an <b>HTML</b> email.</p>'; // 发送邮件 $mail->send(); echo 'Message has been sent using PHPMailer'; } catch (Exception $e) { echo 'Message could not be sent. Error: ', $mail->ErrorInfo; }
By using PHPMailer, you can reliably send HTML mail without having to manually deal with the complexities of SMTP configuration.

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

RESTAPI design principles include resource definition, URI design, HTTP method usage, status code usage, version control, and HATEOAS. 1. Resources should be represented by nouns and maintained at a hierarchy. 2. HTTP methods should conform to their semantics, such as GET is used to obtain resources. 3. The status code should be used correctly, such as 404 means that the resource does not exist. 4. Version control can be implemented through URI or header. 5. HATEOAS boots client operations through links in response.

In PHP, exception handling is achieved through the try, catch, finally, and throw keywords. 1) The try block surrounds the code that may throw exceptions; 2) The catch block handles exceptions; 3) Finally block ensures that the code is always executed; 4) throw is used to manually throw exceptions. These mechanisms help improve the robustness and maintainability of your code.

The main function of anonymous classes in PHP is to create one-time objects. 1. Anonymous classes allow classes without names to be directly defined in the code, which is suitable for temporary requirements. 2. They can inherit classes or implement interfaces to increase flexibility. 3. Pay attention to performance and code readability when using it, and avoid repeatedly defining the same anonymous classes.

In PHP, the difference between include, require, include_once, require_once is: 1) include generates a warning and continues to execute, 2) require generates a fatal error and stops execution, 3) include_once and require_once prevent repeated inclusions. The choice of these functions depends on the importance of the file and whether it is necessary to prevent duplicate inclusion. Rational use can improve the readability and maintainability of the code.

There are four main error types in PHP: 1.Notice: the slightest, will not interrupt the program, such as accessing undefined variables; 2. Warning: serious than Notice, will not terminate the program, such as containing no files; 3. FatalError: the most serious, will terminate the program, such as calling no function; 4. ParseError: syntax error, will prevent the program from being executed, such as forgetting to add the end tag.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.
